The first image might surprise the viewer – it doesn’t look anything like the species listed. While I have plenty of images of this species in its prime, this collection aims to show what happens when the thallii start to age, weather and eventually die: they get populated by other lichen, eaten by worms/snails or just fade away leaving behind only prothallus. In fact, there are light-colored rings scattered all over the boulders at Devil’s Lake that are prothallii from this species and also Aspicilia caesiocinerea – “ghost circles” as I call them.
